After Raaz, Darna Zaroori Hai and the yet to release Raaz 3, Bipasha Basu has signed her forth horror film titled Aatma. Aatma, directed by Suparn Varma of Ek Khiladi Ek Haseena and Acid Factory fame, revolves around Bipasha's character and her experience with a spirit.

A set has been
specially built on the 21st floor of a building in Andheri for the shooting of Aatma as the story takes place in an apartment in a building. The film has a major twist in the climax and to maintain the confidentiality, only Bipasha, director Suparn Varma and the producers, Kumar Mangat and Abhishek Pathak have the complete script.

Interestingly, Bipasha herself is very scared of horror films and covers her eyes with her hands and watches horror films through the gaps between her fingers, but that doesn't stop her from acting in supernatural thrillers.
